JOURNAL OF VASCULAR SURGERY. Incidence, predictors, and prognosis of in-stent occlusion after endovascular treatment with nitinol stents for femoropopliteal lesions

Tomoharu Dohi, MD , Osamu Iida, MD , Yoshimitsu Soga, MD , Keisuke Hirano, MD , Kenji Suzuki, MD , Mitsuyoshi Takahara, MD , Masaaki Uematsu, MD, PhD , Shinsuke Nanto, MD, PhD

Objective: Widespread use of self-expanding nitinol stent-based endovascular treatment (EVT) for femoropopliteal (FP) lesions has been fueled by its less-invasive nature and modest durability; however, prevalence, predictors and prognosis of in-stent occlusion are undefined and were investigated here.

JOUNAL OF VASCULAR SURGERY. Late graft explants in endovascular aneurysm repair

Eric J. Turney, MD , Sean P. Steenberge, MS , Sean P. Lyden, MD , Matthew J. Eagleton, MD , Sunita D. Srivastava, MD , Timur P. Sarac, MD , Rebecca L. Kelso, MD , Daniel G. Clair, MD

Objective: With more than a decade of use of endovascular aneurysm repair (EVAR), we expect to see a rise in the number of failing endografts. We review a single-center experience with EVAR explants to identify patterns of presentation and understand operative outcomes that may alter clinical management.

JOUNAL OF VASCULAR SURGERY. Outcome and clinical significance of delayed endoleaks after endovascular aneurysm repair

Wei Zhou, MD , Eddie Blay Jr., BA , Vinit Varu, MD , Syed Ali, BS , Michelle Qiushuang Jin, BA , Lisa Sun, MS , Jin Hyun Joh, MD, PhD

Objective: Endovascular aneurysm repair (EVAR) is considered the standard therapy for most patients with abdominal aortic aneurysm (AAA). Endoleak is a well-known EVAR-related complication that requires long-term follow-up. However, patient follow-up is often challenging outside clinical trials. We sought to evaluate the incidence and the effect of delayed endoleaks in a Veterans Administration (VA) health care system where long-term follow-up is ensured.

Background: This study analyzed predictors and the long-term consequence of type II endoleak in a large series of elective endovascular abdominal aneurysm repairs (EVARs).

JOUNAL OF VASCULAR SURGERY. Safety and feasibility of adjunctive dexamethasone infusion into the adventitia of the femoropopliteal artery following endovascular revascularization

Christopher D. Owens, MD, MSc , Warren J. Gasper, MD , Joy P. Walker, MD , Hugh F. Alley, BA , Michael S. Conte, MD , S. Marlene Grenon, MD

Objective: Restenosis following endovascular treatment of the femoropopliteal segment is associated with the inflammatory response produced in the artery wall at the time of the procedure. Although local drug delivery to the superficial femoral and popliteal arteries promises improved patency, data are currently limited. We hypothesized that improved percutaneous delivery of an anti-inflammatory compound into the adventitia of the femoropopliteal at the time of endovascular treatment would be safe, feasible, and decrease the inflammatory response.

JOUNAL OF VASCULAR SURGERY. Metabolic syndrome is associated with type II endoleak after endovascular abdominal aortic aneurysm repair

Michael R. Hall, MD , Clinton D. Protack, MD , Roland Assi, MD , Willis T. Williams, MD , Daniel J. Wong, BS , Daniel Lu, BS , Bart E. Muhs, MD, PhD , Alan Dardik, MD, PhD

Objective: Type II endoleak is usually a benign finding after endovascular abdominal aortic aneurysm repair (EVAR). In some patients, however, type II endoleak leads to aneurysm sac expansion and the need for further intervention. We examined which factors, in particular the components of metabolic syndrome (MetS), would lead to an increase risk of endoleak after EVAR.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Anatomic Risk Factors for Type-2 Endoleak Following EVAR: A Retrospective Review of Preoperative CT Angiography in 326 patients

Thomas J. Ward, Stuart Cohen, Rahul S. Patel, Edward Kim, Aaron M. Fischman, Francis S. Nowakowski, Sharif H. Ellozy, Peter L. Faries, Michael L. Marin, Robert A. Lookstein

Purpose: We describe the anatomic characteristics on preoperative CT angiography (CTA) that predispose to type-2 endoleaks after endovascular aneurysm repair (EVAR) for an abdominal aortic aneurysms (AAA).

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Embolization of the Internal Iliac Artery Before EVAR: Is It Effective? Is It Safe? Which Technique Should Be Used?

Joo-Young Chun, Leto Mailli, Maaz Ali Abbasi, Anna-Maria Belli, Michael Gonsalves, Graham Munneke, Lakshmi Ratnam, Ian M. Loftus, Robert Morgan

Purpose: To assess the clinical outcomes of internal iliac artery (IIA) embolization before endovascular aneurysm repair (EVAR).

Akhmadu Muradi, Masato Yamaguchi, Takuya Okada, Yoshikatsu Nomura, Koji Idoguchi, Eisuke Ueshima, Noriaki Sakamoto, Ryota Kawasaki, Yutaka Okita, Koji Sugimoto

Purpose: This study was designed to analyze the outcomes of endovascular treatment for internal iliac artery aneurysm (IIAA) at mid-term follow-up.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Endovascular Aortic Repair With the Chimney Technique Using the Ultra Low–Profile Ovation Stent-Graft for Juxtarenal Aneurysms Having Small Iliac Access Vessels

Alexander Massmann, Ferdinand Serracino-Inglott, Arno Buecker

Purpose: To report the first experience using the chimney technique in combination with the latest-generation low-profile stent-graft to seal abdominal aortic aneurysms having a very short neck (proximal sealing zone) and difficult access due to very small iliac vessels.

RADIOLOGY. Volumetric Quantification of Type II Endoleaks: An Indicator for Aneurysm Sac Growth Following Endovascular Abdominal Aortic Aneurysm Repair

Purpose: To test the hypothesis that type II endoleak cavity volume (ECV) and endoleak cavity diameter (ECD) measurements are accurate indicators of aneurysm sac volume (ASV) enlargement in patients who undergo endovascular aneurysm repair (EVAR) in the abdominal aorta.

JOURNAL OF VASCULAR SURGERY. Comparative effectiveness of endovascular versus open repair of ruptured abdominal aortic aneurysm in the Medicare population

Samuel T. Edwards, MD , Marc L. Schermerhorn, MD , A. James O Malley, PhD , Rodney P. Bensley, MD , Rob Hurks, MD, PhD , Philip Cotterill, PhD , Bruce E. Landon, MD, MBA, MSc

Objective: Endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) is increasingly used for emergent treatment of ruptured AAA (rAAA). We sought to compare the perioperative and long-term mortality, procedure-related complications, and rates of reintervention of EVAR vs open aortic repair of rAAA in Medicare beneficiaries.

JOURNAL OF VASCULAR SURGERY. Experience with a novel custom-made fenestrated stent graft in the repair of juxtarenal and type IV thoracoabdominal aneurysms

Alexander E. Rolls, MRCS , Michael Jenkins, MS, FRCS , Colin D. Bicknell, MD, FRCS , Celia V. Riga, MD, MRCS , Nick J. Cheshire, MD, FRCS , Nick Burfitt, FRCR , Mohamad Hamady, MD, FRCR

Objective: Fenestrated stent grafting has become increasingly popular as a means to manage complex aortic pathology, including juxta- and pararenal aneurysms. The design of a recently developed custom-made fenestrated stent graft, in theory, confers advantages when managing anatomically challenging aortic morphology. This study evaluated its feasibility in anatomically challenging scenarios.
